The Helix Race is the top-of-the-line aluminum crankset, with XC weight and EWS-worthy Enduro strength. Forged AL6066-T6 crank arms were engineered to maximize stiffness and strength while minimizing excess material. Massive amounts of CNC optimization can be seen on almost every surface, creating an eye-popping, top-tier technical aesthetic and weight savings. A 30mm diameter, forged AL7050-T7 spindle delivers added stiffness and further reduced overall weight. e*thirteen's P3 spindle interface and updated self-extractor bolt system promises ease of service for years to come. Helix Race cranks are compatible with Boost and SuperBoost chainlines via versatile flip-flop Helix Race Chainrings, which come in a full spectrum of Helix colors, allowing matching with Helix cassettes and other e*thirteen components. e*thirteen's exclusive, creak-free proven Quick Connect interface keeps the system secure, and Helix rings are fully cross-compatible with both Shimano™ and Sram™ 11 and 12-speed drivetrains, future-proofing your ride. Helix Race Cranks include our newest APS preload adjuster system and custom crank strike boots to keep these beauties looking fresh.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eTech Specs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eChainline: Compatible with Helix Rings to achieve a 52mm Boost or 55mm Super Boost Chainline.
